<div class="textblock"><p>This file consists of a polled mode design example which uses the Xilinx IIC device in dynamic mode and low-level driver to exercise the EEPROM. </p>
<p>The <a class="el" href="group___overview.html#gadeaf11cda2466ae1c6036a3de0f52874" title="Send data as a master on the IIC bus. ">XIic_DynSend()</a> API is used to transmit the data and <a class="el" href="group___overview.html#ga9979fbd483e1c8c495c9eb2bfd7ad6e9" title="Receive data as a master on the IIC bus. ">XIic_DynRecv()</a> API is used to receive the data.</p>
<p>The example is tested on ML300/ML310/ML403/ML501/ML507/ML510 Xilinx boards.</p>
<p>The ML310/ML410/ML510 boards have a on-board 64 Kb serial IIC EEPROM (Microchip 24LC64A). The WP pin of the IIC EEPROM is hardwired to ground on this board.</p>
<p>The ML300 board has an on-board 32 Kb serial IIC EEPROM(Microchip 24LC32A). The WP pin of the IIC EEPROM has to be connected to ground for this example. The WP is connected to pin Y3 of the FPGA.</p>
<p>The ML403 board has an on-board 4 Kb serial IIC EEPROM(Microchip 24LC04A). The WP pin of the IIC EEPROM is hardwired to ground on this board.</p>
<p>The ML501/ML505/ML507/ML605/SP601/SP605 boards have an on-board 8 Kb serial IIC EEPROM(STM M24C08). The WP pin of the IIC EEPROM is hardwired to ground on these boards.</p>
<p>The AddressType for ML300/ML310/ML410/ML510 boards should be u16 as the address pointer in the on board EEPROM is 2 bytes.</p>
<p>The AddressType for ML403/ML501/ML505/ML507/ML605/SP601/SP605 boards should be u8 as the address pointer for the on board EEPROM is 1 byte.</p>
<p>The 7 bit IIC Slave address of the IIC EEPROM on the ML300/ML310/ML410/ML403/ ML501/ML505/ML507/ML510 boards is 0x50. The 7 bit IIC Slave address of the IIC EEPROM on the ML605/SP601/SP605 boards is 0x54. Refer to the User Guide's of the respective boards for further information about the IIC slave address of IIC EEPROM's.</p>
<p>The define EEPROM_ADDRESS in this file needs to be changed depending on the board on which this example is to be run.</p>
<p>This code assumes that no Operating System is being used.</p>

1.00a mta  03/20/06 Created.
2.00a sdm  09/22/09 Converted all register accesses to 32 bit access.
2.01a ktn  03/17/10 Updated the information about the EEPROM's used on
              ML605/SP601/SP605 boards. Updated the example so that it
              can be used to access the entire IIC EEPROM for devices
              like M24C04/M24C08 that use LSB bits of the IIC device
              select code (IIC slave address) to specify the higher
              address bits of the EEPROM internal address.
3.3   sk    06/18/16 checked bytes written with the input byte count and
                     returns error if the value is not matched.
3.4   ms   01/23/17 Added xil_printf statement in main function to
                    ensure that "Successfully ran" and "Failed" strings
                    are available in all examples. This is a fix for
                    CR-965028.
      ms   04/05/17 Modified Comment lines in functions to
                    recognize it as documentation block for doxygen
                    generation.
3.10  gm   07/09/23 Added SDT support.
